Shoei Neotec Helmet Liner Replacement liner for Shoei Neotec helmets. All Neotec helmets come stock with 9MM liners, except the 2XL helmets, which come stock with a 5MM liner. Note: Due to manufacturer restrictions, Shoei products can only be shipped to addresses within the United States.

The thicker centerpad filled the gap directly overhead, raising the fit slightly as I'd hoped. It also resulted in a significant reduction in wind noise. I tend toward an oval head shape and Shoei helmets are generally round/neutral. The thicker centerpad accentuated the 'roundness' across my forehead and was uncomfortable after an hour or so. This has gone away with break-in.
